Abstract

The present invention addresses the problem of capturing an image of a strain state of a bend outside surface of a test piece by a camera without defocus during bend tests. This device for bend tests on a metal sheet for an automobile body is characterized by comprising a support member (1) for supporting two support parts (2) for a flat test piece (P) composed of a metal sheet for an automobile body, a punch (4) for performing bend tests involving bending the test piece (P) by pressing a portion of the test piece (P) between the two support parts (2) from the side opposite to the support member (1) side, and a camera (5) for capturing an image of a bend outside surface of the test piece (P) during bend tests by means of the punch (4) from the support member side, and also characterized in that the relative positions of the punch (4) and the camera (5) during the bend tests are fixed.
